Besides $ ext{CO}_2$, what potent greenhouse gas is released when permafrost thaws?
Answer
Methane ($ ext{CH}_4$)
The thawing of permafrost allows microbes to decompose organic matter, releasing both carbon dioxide and methane. Methane is noted as being significantly more powerful at trapping heat than $ ext{CO}_2$ over a 20-year period.
